Why I'm using unstable repos

Hi guys, I saw a post asking for people to let you know why we were using the unstable repos. I'm not sure why others are using it but for me it was because there were some features or problems which I found the current distributions KDE packages which I was hoping ( or were ) fixed in the newer packages. Initially it was because the plasma-networkmanager app , kopete and quassel were available. I don't have alot of ram in some of my machines so I didn't really want to run KDE 3 apps in kde4 as they can't take advantage of the libraries that are already loaded. I also saw it as a way to test kdevelop4.
